Sažetak
A 4-year study (2006-2009) with three irrigation regimes (A= control variant without irrigation, A2= 60–100 % Field Water Capacity (FWC), A3= 80– 100 % FWC), three levels of nitrogen fertilizer (B1= control variant without any nitrogen fertilizer, B2= 100 kg N ha-1, B3= 200 kg N ha-1), and four genotypes (C1 = OSSK596 ; C2 = OSSK617 ; C3 = OSSK602 ; C4 = OSSK552 ) with similar vegetation length (FAO 500 and FAO 600) were conducted on trial fields of Agricultural institute in Osijek. Vegetation seasons where quite different regarding weather conditions, mean air temperatures and precipitation quantity. Although all four years of research where unfavorable for maize production, years 2007 and 2009 where especially unfavorable because of the severe drought. Aim of the study was to evaluate influence of genotype, nitrogen fertilizer and available amount of water to maize yield and hectoliter weight as quality parameter. Irrigation treatment was significant for all four years of experiment with yield increasing for 13%, and for hectoliter mass in dry years 2007 and 2009 as well, but with the slightly decreasing. Nitrogen fertilizer increased maize yield (for 16%) and hectoliter mass as well. Maize yield (C1 = 9259 kg ha-1 ; C2 = 9814 kg ha-1) and hectoliter mass (C3 = 66.619 kg ; C4 = 72.453 kg) varied thru tested genotypes.
